title: Is personal and social functioning associated with subjective quality of life in schizophrenia patients living in the community?
abstract: Subjective quality of life (QoL) and psychosocial functioning constitute important treatment outcomes in schizophrenia. We aimed to investigate the relationship between them in schizophrenia patients living in the community. Symptom severity and insight were assessed with the Positive and Negative Syndrome Scale (PANSS) in 76 community schizophrenia patients. Social functioning was measured with the Portuguese version of Personal and Social Performance (PSP) scale, and subjective QoL was measured with the Portuguese version of the WHO Quality of Life Measure-Abbreviated Version (WHOQOL-Bref). The majority of patients were single (78%) and unemployed/inactive (74%). Mean PSP total score was 55.5, and mean scores on WHOQOL-Bref domains ranged from 54.1 to 63.0. Greater symptom severity and worse insight were significantly associated with worse functioning in all PSP domains. Symptoms were more moderately correlated with QoL, with no significant correlations between QoL and positive symptoms and insight levels. Partial correlations controlling for symptom severity revealed no significant associations between social functioning and subjective QoL. Symptom severity may exert a greater influence on social functioning than on subjective QoL; however, social functioning was not associated with subjective QoL. The results suggest these constructs might be independent and should be assessed separately. A broader research approach, with increased attention to social and psychological factors, may help identify treatment targets to improve schizophrenia patients' social functioning and QoL.
